1 gru 2009 · Numpy's meshgrid is very useful for converting two vectors to a coordinate grid. What is the easiest way to extend this to three dimensions? So given three vectors x, y, and z, construct 3x3D arrays (instead of 2x2D arrays) which can be used as coordinates.
import matplotlib.pyplot as plt import numpy as np from matplotlib import cm plt.style.use('_mpl-gallery') # Make data X = np.arange(-5, 5, 0.25) Y = np.arange(-5, 5, 0.25) X, Y = np.meshgrid(X, Y) R = np.sqrt(X**2 + Y**2) Z = np.sin(R) # Plot the surface fig, ax = plt.subplots(subplot_kw={"projection": "3d"}) ax.plot_surface(X, Y, Z, vmin=Z ...
A mesh can be created using the np.meshgrid function in Python. The meshgrid function has the inputs x and y are lists containing the independent data set. The output variables X and Y are as described earlier. TRY IT! Create a mesh for x = [1, 2, 3, 4] and y = [3, 4, 5] using the meshgrid function.
We define X and Y as 1D arrays and then use np.meshgrid to create 2D coordinate arrays. The Z array is calculated as a function of X and Y. We then create a figure and a 3D axis, and use plot_surface to create the surface plot. Finally, we set labels and a title, and display the plot.
numpy.meshgrid(*xi, copy=True, sparse=False, indexing='xy') [source] #. Return a tuple of coordinate matrices from coordinate vectors. Make N-D coordinate arrays for vectorized evaluations of N-D scalar/vector fields over N-D grids, given one-dimensional coordinate arrays x1, x2,…, xn.
3D box surface plot # Given data on a gridded volume X, Y, Z, this example plots the data values on the volume surfaces. The strategy is to select the data from each surface and plot contours separately using axes3d.Axes3D.contourf with appropriate parameters zdir and offset.
